For example, let us assume
that the input region of <a href="gen_contour_region_xld.html"><code><span data-if="hdevelop" style="display:inline">gen_contour_region_xld</span><span data-if="c" style="display:none">gen_contour_region_xld</span><span data-if="cpp" style="display:none">GenContourRegionXld</span><span data-if="com" style="display:none">GenContourRegionXld</span><span data-if="dotnet" style="display:none">GenContourRegionXld</span><span data-if="python" style="display:none">gen_contour_region_xld</span></code></a> consists of
the single pixel (1,1).  Then, the resulting contour that is
obtained when calling <a href="gen_contour_region_xld.html"><code><span data-if="hdevelop" style="display:inline">gen_contour_region_xld</span><span data-if="c" style="display:none">gen_contour_region_xld</span><span data-if="cpp" style="display:none">GenContourRegionXld</span><span data-if="com" style="display:none">GenContourRegionXld</span><span data-if="dotnet" style="display:none">GenContourRegionXld</span><span data-if="python" style="display:none">gen_contour_region_xld</span></code></a> with

(0.5,0.5), (0.5,1.5), (1.5,1.5), (1.5,0.5), and (0.5,0.5).
Consequently, when passing this contour again to
<code><span data-if="hdevelop" style="display:inline">gen_region_contour_xld</span><span data-if="c" style="display:none">gen_region_contour_xld</span><span data-if="cpp" style="display:none">GenRegionContourXld</span><span data-if="com" style="display:none">GenRegionContourXld</span><span data-if="dotnet" style="display:none">GenRegionContourXld</span><span data-if="python" style="display:none">gen_region_contour_xld</span></code>, the resulting region consists of the
